- E. H. F'AHRNEY SNOWPLOW Filed May 25. 1925 l atented lll, l

application filed May 25, 'llltlli.

'lhis invention relates in general to soon plows oi the type in Which there Is employed a rotary illlpellm tor delivering; the snow from the u'iachinc, but more specifically the invention relates to improved means adapted for use in connection with the iu'ipeller whereby the snow or matter handled by the impeller will be deflected to one side of the impeller and. Which means also serves to prevent the ma erial from piling up and obstructing; the delivery ot the material trom the chute ot the impeller.

A further object is to provide an int proved device ot this character which may be readily detached trom and readily applied to the machine.

To the attainment cl these ends and the accomplishment ol? other new and. useful. objects as will appear, the invention consists in the features oll' novelty in substantially the construction, combination and arrangement ot the several parts hereinatter more hilly described. and claimed and shown in the accompanying drawing illustrating this inven: tion, and in which Figure l is tront plan "View oi the scoop of a snow plow and impeller with a ca sine; tor the impeller., and chute having an at tachlnent applied thereto constructed in. ac cordance With the principles of this invention.

Figure 2 is a detail top plan View oi the attachment.

Referring: more particularly to the dream leg the numeral designates generally a scoop having; an opening 11. in the bottom thereof, beneath which openiiugis arranged an impeller oil any suitable construction. The impeller casing is provided with a dolivery or discharge chute 13 open at its end as at l l. All of? the above roterred to parts may be oi" any des red and suitable construe tion.

fdupported in any suitable manner a di aceut the outlet oil the chute is 2. "time of any suitable coustructicm and gnated; generally by the reference numeral. l5. This frame is detachably secured in position in any suitable manner preferably by means oil fastening bolts or devices 16, which latter are connected with suitable brackets it. These brackets may be of any suitable construction and may be secured in; any suitable manner to the or casiu 5.11. preil erably to the exterior ol? th 1 :lircry chute 9 (the t ose it prc'hirichly p tlori. a]. lie. 32,5 till.

the extremity of the outlet oi. the chute l3 and plates or members iii maybe supported by the frame, the l lltlllQ members being); tied or fastened together by means of a suitable connecting; member or plate 19. Supported by the it one thus formed and in advance of the e. emity oi the chute are suitable brackets -431 which respectively form bearings for shafts E22--98 and. to which shatts are respectively connected sprocket Wheels il l ilh,

Edupported also by the frame and at any desired point in the rear ot' the brackets 20 and 21 are additional brackets 26 in which a shaft 2? is iournaled.., and to which shalt sprocket Wheels 528 are connected.

Endless chains E29 pass over the respective sprocket Wheels, and connected With. these chains and extending across the SIJACG there between are elements 30, and which. elements are adapted to be successively moved during; the travel of the chains 29 so as to extend across but .in advance olthe outlet ll ot the chute 13, so that material directed through the chute 13 by the impeller 12 will contact with the elements 30 which are in alinement with the end of the chute to dellect the material laterally with respect to the chute. The endless element thus constructed is adapted to be given a constant direction of rotation in any suitable manner and is constantly rotating during; the operation of the machine so as not only to deflect the material discharged from the chute but also operates as a means for preventing; the material from clogging at the outlet of the chute.

A simple and eiiicient means for imparting motion to the endless element embodies a pulley Wheel Ell. which is connected with the shaft fl'l" tor rotation therewith, and n'iotiou may be imparted to the pulley Wheel ill in any suitable manner but preferably :Froin some suitable moving; part of the mechaoisin.

.luides are preterably supported by the Frame 15 to support and guide. the elements 30 as they pass across the end oil the chute and these guides preferably arch From one ide oi the chute to the other, as shown in F gore l.

l l hen desired the endless element and the supportino trame it; may be readily removed by detaching; the fastening; belts or deric s ll.

l i hile the be understood that various changes may be made in the details of construction and in the combination and arrangement of the sev eral parts, within the scope Ofli the claims, Without departing from the spirit of this invention.

What is claimed as new is 1. In combination, an impeller, a casing therefor having a discharge outlet, and a traveling abutment operating independently of the impeller and disposed adjacent the said outlet and extending in a direction across the outlet for directingthe course of travel of thematerial delivered through said out- ,let. i 5 .2. In combination, an impeller, a casing therefor having a discharge outlet, a movableabutn'lent independent-of the impeller and disposed adjacent and extending across ,thesaidout-let i'or d-eflecting the material delivered through said outlet, andmeans for impartingomovement tolthesaid abutment with respect. to the said-casing.

3. In combination, animpeller, a casing therefor havingavdischarge outlet,.-a movnable abutmentindependent ot' the impeller and disposed adjacent and extending across the said outlet {or deflecting the material delivered through said outlet, means for im "parting movement to the said abutment with respecttothe saidcasing, and means detaclr zablysecurin :said abutment in position.

4..'Inc0m ination a discharge chute, an impeller spacedfrom the outlet end there- ,of, an abutment, disposed adjacent the outlet of'the chutevand against which the material strikes after it leaves the impeller, said abutment operating to deflect the material dcliver-ed through the chute, and means for imparting motionvto the abutment to cause the same to travel across the outlet o'l' the chute.

.5. Iii-combination, a chute having a discharge outlet,an impeller spaced from the outlet, a traveling abutment spaced from the impeller [and arranged adjacent the outlet @and extending thereacross and. againstwhich the material strikes after leaving the impel- 'lcr,,said abutment operating to deflect the materialdelivered throughithe outlet, and .meansvforimoving the abutment ina constant direction and transversely of the said outlet.

In combinatiomachute having a discharge outlet, a traveling abutment arranged adjacent the outlet and extending thereacross 'lor deflecting the material dolivcrcd through the outlet, means l'or moving the abutn'ient in a constant direction and transversely ol the said outlet, and means removably securing the said aluitnuml in position.

7. in combination, a chute having :1 discharge outlet, an endless traveling abutment adjacent the chute, one run o l the abutment extending transversely oi" the said utlet lor deflecting the material dclivcrco lhrough the chute, means for imparting motion to the abutment, and means dctucluibl' :ccurcd lo the chute for supporti 1, said abutment.

-8. In combination, :1 chute having, :1 discharge outlet. an endlcrs ""cling clcnu-u supported adjacent ll c sa d ouilcr, one run otthe said clement tr:vvcliu; across and spaced from the end oi the said outlet l'or deflecting the material delivered through said outlet, and means for imparting move,- ment to the said endless clement.

9.111 combination, a chute having a dire charge outlet, an endless traveling elcnicnl supported adjacent the said outlet, one run of the said element traveling across and spaced from the end of the said outlet lor deflecting the material delivered through said outlet, means for inn arting-movcmcnt tothe said endless element, and means ex tending l'or a considerable distance along the path cl movement of the said run of the said endless element for supporting and guiding the same.

10. In combination, a chute having a dis-- charge outlct, an endless traveling clcmcut supported adprcentlhc said outlet, one run .otthc said elemcul. arching: across the said charge outlet, an endles trave ing clement supported .ot the said element arcln A adjacent the said outlet, one run across the said outlet from one side thcreol. and operating to laterally deflect the material dclivcrcd ,throu 'h the said outlet and thereaga inst and means for imparting a traveling movement I to the said endless elemcnl.

In testimony \vhcreo'l i have siguml my name to this specification, on this lllh day of Na), 1925.
